You are acting like this is news. The whole point of Rishta is that family approval is important. Even during Abhira's case, the family wasn't agreeing, so they spent a lot of time trying to convince them. So yeah, family approval is important, and marrying a stranger that your family hasn't even seen or heard of is insane.
Moreover, even in situations where people elope, it's cause of love, not convenience. I know that love isn't the only reason people marry, but it should be the only reason. That's the whole point. No one is saying Ak is stupid or dumb for randomly marrying a stranger. But her mistakes are there, and if people are commenting on it, what's wrong?
Abhi's mistakes have been talked about and discussed plenty of times. He has not been given a pass for white day; people just understand his situation. As in, a lot of people in a similar situation think they would have had the same reaction. With Ak its less so. I personally would have never trusted a stranger over my family, no matter how estranged I get from them. And here, it's not like the Goenkas even did anything. They always supported Arohi over Ak and did blame Ak for the deaths - but they still wanted to be there for her and support her. If Ak didn't want to go back to Udaipur, she could have just asked for financial help; why not? It's still her money. She could have gone through the pregnancy at a proper place with all the amenities. Nav can still be there for support. And if Ak did fall in love with Nav eventually, then her marrying him makes sense - even without family approval.
But here, she refused her family's help, lived in horrible conditions during a complicated pregnancy, and essentially burdened a stranger into taking care of her. Then after she nearly died during childbirth, she woke up and saw how much this stranger did for her. At this point, I agree Nav is no longer a stranger. But....she still didn't trust him with her heart. She literally married him to have a substitute father for her son, so her decision of not informing Abhi would be justified in her eyes. Even after all this, she still refused to become independent or anything. After six years, she is still depending on her "husband" to run the household.
The whole situation and her reasoning for her actions aren't clear so people are still questioning it. Even during the first leap her actions and reasoning were bad. It's just a trend with the character, and they have written her so poorly it's hard to root for her.
